There is a minimal chance that this will happen but of course it could be possible, the bitcoin is already so big that it cannot disappear right away in my eyes.
It would take years to destroy it fully..
And I believe it will not happen soon, we will be enjoying more the benefits of using bitcoin. It is the new digital currency that is going to be useful for the people who love to transact online as it can help them save for the expenses on the fees, so I guess it will not be destroyed or will disappear, unless the government ban this.
Even though government would ban bitcoin there would be still transaction underground which we could really say that bitcoin would not disappear anytime soon as long its been used by people. You are right there are lots of benefits we could make in bitcoin thats why we cant think as of now that it would disappear.
At this moment, bitcoin has a lot of benefit and that is why it is attracting a lot of people. First it is the ease of trading across the global. With no 3 days waiting, no bank to bank transaction fee, no conversion rate problems, fast and secure, one of the lowest fee for buying and selling platform, the demand for btc is sure to increase during these few years.
Yes and once more people get aware about it, it will surely take adoption to higher level in future and that will directly contribute in taking price to next level and bitcoin will become more powerful as a currency in future.
